lipplicatiou filed July 28. 1906. Serial No- 328234.

To all whom it may concern:

Be it known that I, ALBERT F. GEORGE, citizen of the United States, residing at Bisbee, in the county of Cochise and Territory of Arizona, have invented certain new and useful Improvements in i/Vindmills, of which the following is a s ecification.

My invention re ates to improvements in windmills.

The object of my invention is to provide in a windmill having a plurality of wind wheels novel means for supporting the windwheels on a single tower in a manner such that the support carrying the wheels will be evenly balanced as to the weight of the windwheels and the wind pressure upon them.

My invention provides further novel governing means for controlling the throwing into and out of the wind of the windwheels carried by the revolving sup ort. Other novel features are liereinafter'fully described and claimed.

In the accompanying drawings illustrative of my invention, Figure 1 1s a front elevation view of my improved windmill, with the windwheels and vanes shown thrown out of the wind, the upper part only of the tower being shown. Fig. 2 is a plan view of what is shown in Fig. 1, some of the parts being broken away and the pivoted vane being shown in dotted lines disposed transversely to the faces of the windwheels. Fig. 3 is a vertical central sectional view of the automatic means for locking the pivoted vane, the vane shank being shown engaged.

Similar characters of reference denote similar parts.

1 denotes the ordinary tower having secured to its upper end a horizontal annular plate 2 having in its upper side an annular ball race 3 having therein a series of balls 4 located also in a similar ball race in the under side of a horizontal annular plate 5 which supports upon its upper side a support or truss 6 preferably constructed of steel bars joined together in the manner of an ordinary bridge truss. Rotatively mounted on the truss or support 6 are two pairs of horizontal shafts 7 disposed at opposite sides of a vertical plane intersecting transversely to the support 6 the axis of revolution of said support, said plane being parallel also with the shafts 7. The shafts 7 of each pair are disposed at of revolution of the opposite sides of a vertical plane intersecting t e axis of revolution of the support 6 at right angles to the transverse plane. The shafts of each pair have the same axis. Four windwheels 8 are secured respectively upon said shafts 7, and outside the support 6, the windwheels being disposed in two pairs and the wind wheels of each pair being located one in front of the other.

The blades 9 of the windwheels of each pair are inclined in op osite directions, so that the wind passing t rough the forward wheels will strike the rear wheels so as to rotate the rear wheels oppositely to the direction of rotation of the forward wheels.

To prevent teetering of the frame or support 6, corresponding windwheels of the two pairs may have their blades inclined oppositely so that corresponding wheels will rotate in opposite directions.

Rotatively mounted on the support 6 in suitable bearings is a longitudinal horizontal driving shaft 10 disposed in the vertical plane which intersects longitudinally the axis support 6. The shaft 10 is provided with a crank 11 to which is pivoted the upper end of a downwardly extending pitman 12 which may be employed to operate a pump, not shown, or perform other desired service. The crank 11 is located at the intersection of the longitudinal and transverse planes above mentioned.

Opposite ends of the driving shaft 10 have secured thereon bevel gears 18 which mesh respectively with bevel gears 14 secured one to each shaft 7 at its inner end. By means of these gears movement in a like direction is imparted to the driving shaft 10.

At one end of the support 6 intermediate the adjacent windwheels 8 is secured an auxiliary vane 15 disposed parallel with the shaft 10, and preferably in the same vertical plane, the vane having its fiat sides disposed parallel with the faces of the windwheels 8.

I A steering vane 16 is pivoted on a vertical axis located in the central transverse vertical plane intersecting the axis of revolution of the support 6. The vane 16 has secured to it a horizontal arm 17 extending rearward at an angle to the vane 16 and by means of which the vane is retracted to the position shown in dotted lines in Fig. 2, in which position the support 6 will be swung so that the faces of the wind wheels 8 will be in the wind. The axis of the vane 16 is preferably a vertical bar 18 to which the vane is secured and which is rotatively mounted in suitable bearings in the support 6.

To swing the vane 16 to the position shown in dotted lines in Fig. 2, a'flexible device such as a rope 19 has one end secured to the outer end of the arm 17, said rope passing .over a pulley 20 secured on the support 6 and having its lower end extending downward from said pulley and secured to a member comprising preferably a bar 21 one end of which is secured pivotally to the support 6. On the bar 21 is secured a weight 22, which is adjustable lengthwise of the bar and is secured in position thereon by a set screw 23. The pressure of the weight normally, by bearing down on the rope 19, pulls the arm 17 so as to swing the vane 16 to the position shown in dotted lines in Fig. 2. To man ually retract the vane 16 to the position shown in solid lines in Figs. 1 and 2, in which position the wheels 8 will be thrown out of the wind, a rope 24 has one end secured to the shank of the vane 16 and passes therefrom horizontally against a pulley 25 rotatable on a vertical axis and supported on the support 6. The rope 24 passes thence horizontally to apulley 26 pivoted on a horizontal axis to the support 6, and thence downwardly through the central openings in the annular plates 2 and 5.

Releasable automatic locking means for holding the vane 16 in the position shown in solid lines in Figs. 1 and 2 are provided comprising preferably the following described mechanism, referring particularly to Fig. 3.

Upon the upper and rear side of the suport 6 to the rear of the pulley 25 is a bracket 27 having two rearwardly. extending horizontal arms 28 and 29 disposed one above the other and adapted to receive between them the shank 30 of the vane 6 when the vane is swung by the wind or manually to the position shown in solid lines in Figs. 1 and 2. The lower arm 29 has on its underside a U shaped extension 31, the horizontal portion of which is provided with a vertical holein which is slidably mounted. a locking bolt 32, the upper end of which extends through a vertical hole in the arm 29 and is beveled rearwardly and downwardly, as shown in Fig. 3, so that when the shank 30 of the vane 6 enters the bracket between the arms 28 and 29, the bolt 32 will be depressed to allow the shank to pass beyond said bolt. A coil spring 33 encircles the bolt 32, the lower end bearing upon the horizontal portion of the extension 31 and the upper end bearing upon a transverse pin secured in a hole in the bolt 32 below the arm 29, said. pin being denoted by the numeral 34. The tension of spring 33 is such that the bolt 32 is normally held in the position shown in Fig.

sure acting on vane 3. To manually release the shank 30 of the vane 6 from the locking mechanism, the upper end of a rope 35 is secured to the lower end of the bolt 32, said rope passing downward through the openings in the annular plates 2 and 5 to a point where it may be grasped by the operator.

In operating the invention, when the rope 35 is pulled downward, the bolt 32 will be retracted and the weight 22 will then by bearing down on the pivoted bar 21 draw the rope 19 downward and through the intermediacy of the arm 17, the vane 6 with its shank 30 will be swung toward the position shown in dotted lines in Fig. 2. The support 6 will then be swung by the wind pres- 16 to a position in which the wheels 8 will be thrown into or facing the wind. The position taken by the support 6 will depend upon the position of the weight 22 on the bar 21, the weight of said -weight, and the relative area exposed to the wind of the vanes 15 and 16, as well as upon the velocity of the wind blowing at the time. If the wind increases in velocity, the vane 15 will cause the support 6 to be swung so that the windwheels 8 will be thrown more out of the wind, and upon suflicient wind pressure which might damage the mill, the vane 1 5 will cause the support 6 to be swung so that the vane 16 will be automatically engaged by the locking mechanism hereinbefore described. This engagement may be manually made by drawing downward on the rope 24, in which case, the vane 6 may be swung relative to the support 6 so that the shank 30 will enter the bracket 27 between the arms 28 and 29, and, by forcing downward the bolt 32 pass beyond the bolt and be held thereby, the bolt immediately being upwardly moved by the spring 33. By adjusting the weight 22 lengthwise on the bar 21, the governing of the position of the support 6 relative to the wind, and the speed of rotation of the windwheels 8 regulated to suit the purposes of the operator. The length of the rope 19 should be such that the bar 21 will swing above and below a horizontal line intersecting the pivotal point of said bar.

My invention may be modified in difierent ways within the scope of the appended claims without departing from its spirit.
